摘要： A method, system, and article of manufacture for recovering from a track format error detected by a host computer associated with a storage controller associated with a storage disk array. The recovery method begins with saving a copy of the track format information associated with the data track that triggered the track format error in a predetermined location. Next, the track format information associated with the data track that caused the error is invalidated and the subject data is restaged. Subsequently, the restaged data is compared to the saved copy of the track format information to determine if the track format error exists with respect to the restaged data. If the track format error is detected with respect to the restaged data, the method further consists of reconstructing the data, preferably by performing a reconstruct read recovery. The reconstructed data is then compared to the saved copy of the track format information to determine if the track format error exists with respect to the reconstructed data. The method is completed by rebuilding the track format information to match the reconstructed data, writing the reconstructed data to the storage disk array, and passing the reconstructed data to the host.

摘要： A method for media operational queue management in disk storage systems evaluates a plurality of pending storage operations requiring a destage storage operation. A first set of the plurality of pending storage operations is organized in a first array queue grouping (AQG). The AQG is structured such that all of the storage operations are completed within a predefined latency period. A computer-implemented method manages a plurality of pending storage operations in a disk storage system. A pending operation queue is examined to determine a plurality of read and write operations for a first array. A first set of the plurality of read and write operations is grouped into a first array queue grouping (AQG). The first set of the plurality of read and write operations is sent to a redundant array of independent disks (RAID) controller adapter for processing.

摘要： A Redundant Array of Independent Disks (RAID) controller receives new data that is to be written, wherein the new data is indicated in blocks of a first block size. The RAID controller reads old data, and old parity that corresponds to the old data, stored in blocks of a second block size that is larger in size than the first block size. The RAID controller computes new parity based on the new data, the old data, and the old parity. The RAID controller writes the new data and the new parity aligned to the blocks of the second block size, wherein portions of the old data that are not overwritten by the RAID controller are also written to the blocks of the second block size.

摘要： A method according to one embodiment includes defining a new encryption band with a length that is consistent with a redundant array of inexpensive disks (RAID) parity strip; freeing a working extent in a working stride on the RAID. In an iterative process until each stride in a source band is depleted of data: marking a source extent in a source stride from which to gather data to be re-encrypted; marking parity inconsistent in the working stride in the new encryption band; performing a second iterative process; and freeing the working extent. The second iterative process is performed until each extent in a source stride is depleted of data. Additional systems, methods and computer program products are also presented.

摘要： Method, system, and computer program product embodiments for concurrent copy of system configuration global metadata in a data storage system are provided. In one exemplary embodiment, a global data rank is quiesced, followed by an unquiesce of the global data rank except for a global metadata area. The global metadata area is updated in memory, and then unquiesced. A current range of the global metadata area to be copied is quiesced. The current range of the global metadata area is copied from a source area to a target area. The current range is unquiesced. The steps of quiescing an additional current range, copying the range from a source area to a target area, and unquiescing the current range continue until the entire global metadata area has been copied.

摘要： A method for allocating resources of a storage system including at least a first and second group of storage devices. The method identifies a first set of resources to be reserved for use by the first group of storage devices, identifies a second set of resources to be reserved for use by the second group of storage devices, and identifies a third set of resources The method then allocates resources from the third set of resources to the first group of storage devices or the second group of storage device according to an allocation algorithm, and restricts use of the first set of resources to the first group of devices and use of the second set of resources to the second group of devices.
